Nakano Note (Nakano wa Kangaeru noda) NK 3167 C/2015 X5 (PANSTARRS)
The following improved orbital elements, S. Nakano, are from 46 observations 2015 Dec. 6 to 2016 Apr. 4. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.32 arc second. Epoch = 2018 Jan. 2.0 TT T = 2017 Dec. 30.98404 +/- 0.04171 (m.e.)
